As you can tell, I don't really mesh with the style that seems to be the general focus of this website. I have some Journey etc, but most of that stuff is take it or leave it in my book. The best Melodic Rock/AOR (by my definition at least) song I've ever heard is Steel from Bob Catley's The Tower. That is how the genre should sound!
